====== Completion Options ======

''always_last_prompt''
  * if zsh prints out a list (eg. on an ambiguous completion), it reuses the old prompt instead of printing a new one underneath the list; this breaks menucompletion if turned off

''complete_aliases''
  * don't expand aliases _before_ completion has finished

''complete_in_word''
  * if unset the cursor is set to the end of the word if completion is started

''list_ambiguous''
  * complete as much of a completion until it gets ambiguous.

''glob_complete''
  * cycle through globbing matches like menu_complete

''rec_exact''
  * in completion, recognize exact matches even if they are ambiguous.
